@sagas From what I've read/seen English are genetically almost identical to Dutch and northern germans, and have a very large gap to the celts of wales and Ireland. For example James May from top gear was genetested and his ethnicity matched that of the upper rhine valley in Germany. However the English becomes generally closer to the welsh the more west in England you go but I also recall Reading that despite this there is a large difference gentically between welsh and the English living in western England still. The first anglo-saxons was actually invited to Britannia after the roman departure to work as a buffer to ongoing germanic raids, like the romans did on the continent, however this plan backfired.
